Which Medications Cause Parkinsonism?

Drugs that are known to induce parkinsonism include:
  • neuroleptics (antipsychotics)
  • dopamine depleting drugs.
  • antiemetics.
  • calcium-channel blockers.
  • mood stabilizers.
  • antidepressants.
  • antiepileptic drugs.

Is medication induced parkinsonism reversible?

Drug-induced Parkinsonism is often reversible after withdrawal of the causative drug. Its clinical course, however, is not well understood, as the majority of cases are caused by drugs prescribed by departments outside of neurology.

What drugs make Parkinson worse?

These drugs include Prochlorperazine (Compazine), Promethazine (Phenergan), and Metoclopramide (Reglan). They should be avoided. Also, drugs that deplete dopamine such as reserpine and tetrabenazine may worsen Parkinson's disease and parkinsonism and should be avoided in most cases.
